简要总结
The goal of this randomized controlled trial is to evaluate whether a nature-based contemplation intervention can enhance spiritual well-being and reduce grief symptoms among adults with moderate prolonged grief symptoms. The main questions it aims to answer are:
Does a nature-based contemplation intervention improve spiritual well-being compared to an active control condition (noticing nature) and a waitlist control condition?
Does a nature-based contemplation intervention reduce grief severity and improve mental well-being, nature connectedness, selflessness, ability to adapt, personal recovery, and elevation compared to control conditions?
How do spiritual well-being, ability to adapt, nature connectedness, selflessness, grief reactions, and positive/negative affect change during the intervention period?
Researchers will compare a nature-based contemplation intervention to both a noticing-nature active control group and a waitlist control group to isolate mindfulness-specific effects from possible general nature exposure benefits.
Participants will:
Complete baseline, post-intervention, and follow-up assessments (at one and three months) Engage in either 10 sessions of nature-based contemplation practice or noticing nature activities over a two-week period (intervention and active control groups) Provide daily diary responses about their experiences throughout the 14-day intervention period

结局指标
主要结局
Spiritual well-being measured by Spiritual Attitude and Involvement List-Short Form
时间窗: 4 months after baseline
Measured using the Spiritual Attitude and Involvement List-Short Form (SAIL-SF; Bohlmeijer et al., 2023). The SAIL-SF measures seven dimensions of spiritual well-being: meaningfulness, trust, acceptance, caring for others, connectedness with nature, transcendent experiences, and spiritual activities. Each dimension is assessed by one item (e.g., "I experience the things I do as meaningful", "I try to take life as it comes"). Items are rated on a 6-point Likert scale ranging from 1 (not at all) to 6 (to a very high degree), with higher scores indicating greater spiritual well-being. The total score is calculated as the mean of all items.
